Abstract

The surgical treatment of obesity can have adverse effects on bone, but there are few published data on the effects of vertical-banded gastroplasty. Serial measurements of bone mineral density at the lumbar spine and three upper femoral sites, using dual-energy X-ray absorptiometry, and also of biochemical indices of bone and mineral metabolism at intervals up to 2 years after operation were performed in 18 patients with morbid obesity who had vertical-banded gastroplasty. Bone mineral density measurements were also made in age- and sex-matched non-obese controls. Bone density before operation was significantly greater in the obese than in the controls (P<0·02 at all sites). The obese patients lost weight rapidly after vertical-banded gastroplasty (mean weight loss 29 kg at 1 year, P< 0·001). This was accompanied by a measurable loss of bone density from the trochanter and Ward's triangle sites in the upper femur (P<0·05), but not from the lumbar spine. Bone density values remained stable over 14 months in the controls. Hydroxyproline excretion increased significantly (P< 0·005), indicating an increase in bone resorption. Alkaline phosphatase levels decreased significantly (P< 0·001), but this probably represents the reversal of hepatic steatosis. There was no evidence of hyperparathyroidism or vitamin D deficiency. In conclusion, vertical-banded gastroplasty causes modest bone density loss from femoral sites, but not the lumbar spine. The difficulties of assessing bone density changes in the obese are discussed.

  • Sleeve gastrectomy produces weight loss between that of purely restrictive and malabsorptive procedures.

    “Sleeve gastrectomy is becoming increasingly common, with weight loss falling between the purely restrictive and malabsorptive procedures (1 to 2 year weight loss: 20-30%; excess BMI loss: 45-80%).36, 46-50.”

  • In a small prospective study, eight women who underwent sleeve gastrectomy had significant bone loss at the spine (4.6%) and hip (total hip 8.3%, femoral neck 7.1%) at one year.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
